Detailed Description

template<class TCompositor, class TClassifier = vtkVoronoiClassifier2D>
struct vtkVoronoiCore2D< TCompositor, TClassifier >::TopologicalMerge

Functor class used to topologically merge (nearly) coincident points.

It basically sorts topological coordinates, and then assigns a global point id to each run (of identical topological coordinates). The resulting merge map can then be used to generate merged point ids when producing global output. The class depends on the compositor type, which provides the topological coordinates and information about the number of points produced by each tile; and merge tuples, which is the global array that maps tile points into merged global points. On output, this class produces the total number of merged points, and a merge map that maps the tile points into final point ids.

Methods related to merging coincident points.

The number of merged points is the number of remaining points after merging (ie., after removing duplicates). The MergeMap maps the tile point ids (which contain duplicates) to global point ids (no duplicates).
